Restaurant Brands, the NSW partner for Taco Bell, did not provide a new opening date for the Stockland Jesmond-based store when it announced that the November 26 opening for the state's first Taco Bell had to be postponed.

"Due to unforeseen circumstances, the launch of Taco Bell Jesmond... has been postponed as the power needs some urgent adjustments," the company said.

"While disappointing, an additional week will ensure we bring our customers the very best experience Taco Bell has to offer. A new opening date will be announced [this] week."

It came after Restaurant Brands hosted a VIP event at the store on Thursday, November 21 where guests were able to sample some of the food and drink items that will be available on the menu, use the touchscreen ordering kiosks and tour the store.

The Jesmond store already has 56 employees on its books.

Torri Gregory and Brittny Morriss, assistant general managers of the Jesmond store, told The Star they were excited for the grand opening.

"I worked at another fast food chain for 10 years but Taco Bell is so different. It's a completely different vibe - so friendly and fun. The team has really bonded well. We can't wait to start serving customers," Ms Gregory said.

Taco Bell is a popular Mexican fast food chain from the United States.

The chain first tried to launch into Australia in 1981 and then again in 1997 but with no success. It launched into Australia again in 2017, opening seven stores in Queensland which remain open to this day.

The Jesmond store will be the first in NSW, to be followed by another in Blacktown which is expected to open mid-December.

Taco Bell said it looking to open 40 restaurants in Australia in the next five years which would create 2000 jobs.
